These sensors are available as preset or adjustable thermostats, thermocouples, thermistors, RTDs or thermal fuses. They can be integrally mounted (encapsulated in silicone rubber) to sense the temperature of either the part or the heater sheath. The thermostats can also be ordered separate from the heater, allowing direct control of your process temperature, if desired. 531  WATLOW  ® Thermostats and Accessories ST10 and ST207 Temperature Sensors ã T-10 thermostats are manufactured for specific preset temperatures.  Available in 25°F increments.ã Other temperature ranges and voltages are available on special order. Minimum quantities apply, contact your Watlow representative before ordering. Notes: ã When ordering a pre-set thermostat separate from the heater, simply add the prefix S  to the model number. (Example: ST-10) See next page.ã Snap action preset temperatures on the T-207 are close/open settings. Pre-Set Thermostats Several styles of non-adjustable, pre-set thermostats are available from Watlow. Thermostats separate from the heater are encapsulated in silicone rubber, and are available with standard 12 in. (305 mm) leads unless otherwise specified. Thermocouples, thermistors, RTDs and thermal fuses are usually mounted to the heater under a vulcanized protective cap of silicone rubber sheath material.  This drawing shows a typical mounting style for a thermocouple.  1 1  /  2  in.(38 mm) 1 3  /  4   in.   (45 mm) 3  /  4  in.   (19 mm) Ref. 3  /  8  in.   (9.5 mm) T-10 1 1  /  2  in.(38 mm) 1 1  /  4   in.   (32 mm)   3  /  4   in.   (19 mm) Ref. 11  /  16   in.   (17.5 mm) T-207 Pre-Set Thermostats (Non-Adjustable) 2 1  /  2  in.

Pre-set thermostats are encapsulated in silicone rubber with standard 12 inch leads. The same temperature ranges, ratings and sizes are available on these thermostats. When ordering, add “S” prefix to the model number to indicate “separate” item. (Examples: ST-10 and ST-207)Standard leads are 12 in. (305 mm) 18 gauge UL ® 1180 black leads. Note: For direct control of air temperature as is required in enclosure heating applications, specify thermostat model number ST-207E. This is a modified ST-207 mounted on 1  /  32 inch thick G-10 circuit board with the thermostat’s metal cap exposed to sense air temperature.  533  WATLOW  ® Thermostats and Accessories ST10 and ST207 Thermostat Ordering Information Options 0 = None  Sensors 0 = None T10 Set °F  A = 125B = 150E = 175F = 200G = 225H = 250J = 275K = 300 T207 Set °F 1 = 40/552 = 60/753 = 95/1104 = 145/160 Lead Insulation 1 = 1180 UL ®  R/C 2 = 1180 C-UL ® R/C4 = 3134 18 Ga.6 = 1199 CSA 9 = Type E PTFE A = 1180 VDEB = 1199 VDE Lead Length*  A = 8 inB = 12 inE = 18 inF = 24 inG = 30 inH = 36 inJ = 40 inK = 4 ftL = 5 ftM = 6 ftN = 7 ftP = 8 ftR = 9 ftS = 10 ft T = 12 ftU = 15 ft V = 18 ft W  = 20 ft Y = 22 ft1 = 25 ft2 = 30 ft Tstat Part #- 0 0___ Standard lead for T207 is 16 Ga. black.Standard lead for T10 is 22 Ga.. black.* Customer specified length must be noted in inches when ordering.
